[Bioconversion] Usefulness R&D

Sat Feb 11 12:56:43 EST 2006

Dear Mr. Comeau:

Thanks again for your continued interest and support.

I have built four prototypes in two sizes over the years and used and tested 
them extensively.

See the latest at http://www.aaecorp.com/ceo.html and at 
http://www.aaecorp.com .

 I now have a projected price list for ten standard sizes of furnaces. Five 
short (6 foot tall) furnaces and five tall (ten foot tall) models. The short 
units are essentially for residential use and the tall units are for large 
residential and small business and farm applications.

I am interested in entering into collaborative or licensing arrangements 
with interested parties. Favorable terms will be offered. Interest is 
growing all over the world in alternative energy due mainly to higher prices 
for conventional energy, as I'm sure you are well aware.

It isn't really a hard decision to continue with this development project,, 
although it would be very hard to decide not to continue with 2005 again 
going down in the record books as the hottest year on record, and 
international pressure building to address climate change. I'll probably 
give up when they pry my cold dead hands off of this furnace project in 
order to bury me. (smile)
